SPECIFICATION forming part of Letters Patent No. 508,360, dated November 7, 1893.

Application filed February 11, 1893. Serial No. 461,876. (No model.) I

To aZZ whom it may concern:

Be it known that I, WILLIAM WYAND, a citizen of the United States, residing at Atlantic City, in the county of Atlantic and State of New Jersey, have invented certain new and useful Improvements in Mechanical Movements; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. V

This invention relates to improvements in mechanical movements; and it consists of a new and improved system of gearing for transmitting power and converting motion.

The object of the invention is to provide a means for positively rotating a carrier-band for operating various descriptions of machinery, and while the invention is applicable to a variety of purposes it is specially designed to be used in connection with that class of machinesgenerally known asroundabouts,and particularly to machines of the class known as '-.observation towers, in which a large skeletonwheel, mounted vertically between suitable standards or towers in bearings at the top thereof, is caused to revolve slowly, so as to elevate successively a series of carriages which are vertically swung,;- at intervals, at

the periphery of the wheel.

For convenience, I will describe the invention in connection with a roundabout of the class and construction shown and described in an application filed by me January 18, 1893, Serial No. 458,836.

In'providing a machine of this class with my improved gearing, I secure to the wheel, at one side or face thereof, a carrier-band provided, at equi-distant and proper intervals, with transverse slots or perforations which extend entirely through the material of which saidband is constructed. In connection with the band two elastic rollers or disks are employed, one located on the inside and one on the outside of said band, with mechanism for adjusting them to and from the band, and suitable mechanism by which they may be rotated. The elastic natureof the disks causes them to enter the slots or perforations as they successively pass between said disks, thus forming virtually a series of cog-teeth which move the wheel positively.

In the accompanying drawings:Figure 1 represents a side elevation of an observation wheel, showing my improved gearing connected thereto; Fig. 2, a front elevation of the improved gearing and carrier-band; Fig. 3, a rear elevation of the same, showing the mechanism for adjusting the elastic disks or rollers; Fig. 4, a detail View, showing a portion of the carrier-band in longitudinal section, and the rollers or disks, and Fig. 5, a detail top plan view, with the upper gear wheel and a portion of its shaft removed to show the bracket in which is journaled the worm.

Referring to the several views of the drawings:The numeral 1 indicates the framework of the tower, on the top of which is mounted v a bearing-block, 2, in which is journaled one end of a shaft, 3, carrying the large wheel 4. It will be understood that the other end of the shaft is journaled in a similar bearingblock on a similar tower at the opposite side,

and is therefore not necessary to illustrate.

The numeral 5 indicates an annular metal carrier or band which is secured to one side or 'face of the large wheel 4, in any suitable or near their respective ends, are mounted in bearings made in the standards 9 and 9', the former being adjustably mounted in slots 10 of a base-plate, ll, secured to the tower of the machine. the rear of the plate where they are provided with perforated heads through which extends the adjustingscrew 12. The aperture of one of the standards is internally screw- 10c The said standards 9 extend to also provided with a balance wheel, 20, to inthreaded to receive the screw threaded portion of the adjusting screw, while the aperture in the other standard is plain, as is also that portion of the adj usting-screw which is received in said aperture. The adjusting screw is provided with a shoulder, 13, and a collar or jam-nut, 14, at the plain portion thereof, which permit it to turn freely in the plain aperture in the standard, but prevents any longitudinal movement of the screw in said standard. Thus when the screw is turned the standards are moved toward or from each other as the case may be, and the rollers or disks are accordingly adjusted to the carrierband.

The standards 9 are swiveled to the plates 11 in order to allow the shafts to move slightly in the arc of a circle to permit of the adj ustment above described. To the end'of each shaft 8, opposite the end on which the elastic roller or disk is mounted, is secured a coggearwheel, 15, which intermeshes with an intermediate worm, 16, mounted on a shaft, 17, journaled in bearings made in a bracket, 18, secured to the base-plate before mentioned. The said shaft is provided with a pulley, 19, to which power may be applied, by means of a band or belt, from a suitable motor to drive the shaft and impart motion to the gearing to revolve the large Wheel 4. The shaft is sure a steady and uniform movement of the large wheel.

While having described the in vention with reference to the rotation of a large wheel, through the medium of smaller wheels, it will be evident that the action may be reversed and the power applied to the large wheel instead of the small wheel, so as to transmit motion from the larger to the smaller wheel of the train of gearing.

Instead of the transverse slots it is evident that the carrier'band may be provided with circular or other shaped apertures, which will operate in conjunction with the elastic rollers or disks in the sarne manner, as the slots.

The operation of the invention will be readily understood in connection with the above description, and it is'only necessary to state that, the parts being properly adjusted so as to bind the elastic rollers or disks to the carrier band, the elastic peripheries will become embedded in'the slots,and when motion is imparted to the rollers or disks they will form, with the slotted carrier-band, virtually an elastic cog-gear which Will move the large wheel 4, or any other device which it may be desired to move, with a motion that is both positive and steady.

Having thus fully described my invention,

what I claim, and desire to secure by Letters Patent, is

1. In a gearing, the combination, with a perforated carrier-band, of a pair of elastic rollers or disks embracing the same, and mechanism for imparting motion to the rollers or disks, substantially as specified.

2. A mechanical movement for transmitting motion, comprising a perforated carrier-band, a pair of elastic rollers or disks embracing said band, and a Worm and cog-gearing for imparting motion to said rollers and thereby to the band, substantially as specified.

3. In a device for transmitting motion, the combination, with a perforated carrier-band, of a pair of elastic rollers or disks embracing said band and mounted on suitably journaled shafts, mechanism for adjusting said rollers or disks, and a worm and cog-gearing for imparting motion to the rollers or disks, substantially as specified.

4. In a device for transmitting motion, the combination, with a perforated carrier-band, of a pair of elastic rollers ordisks embracing said band, the shafts on which said rollers or disks are mounted, the movablebearings for one end of said shafts and the adjustable bearings for the other end, and mechanism for adjusting the adj ustable bearings, substantially as specified.

5. In a device for transmitting motion, the combination, with a perforated carrier-band, of a pair of elastic rollers or disks, the shafts on which said rollers or disks are mounted,

the movable bearings for one end of saidshafts and the adjustable bearings for the other end, the cog-wheels mounted on the shafts, and the intermediate worm mounted on the main-driving-shaft, substantially as specified.

6. The combination, with a wheel provided with a perforated carrier-band, of a pair of rollers or disks embracing said band, and mechanism for imparting motion to said rollers or disks to rotate the wheel, substantially as specified.

7. The combination, with a wheel provided with a perforated carrier-band, of a pair of rollers ordisks mounted on shafts the shafts and their adjustable bearings, a cog-wheel mounted on each of said shafts, and an intermediate worm mounted on the main driving-shaft, substantially as specified.

In testimony whereof I afi'ix my signature in the presence of two witnesses.

WILLIAM WYAND.
